VENTILATOR.

Specification of Letters Patent.

Application filed December 5, 1910. Serial No. 595,687.

To all whom it may concern:

Be it known that I, EDMOND GAGNON, a subject of the King of England,residing at Montreal, in the Province of Quebec, Canada, have inventedcertain new and useful Improvements in Ventilators; and I do herebydeclare that the following is a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.

The invention to be hereinafter described relates to ventilators andmore particularly to ventilators of the fan type.

It is especially designed for domestic use.

In order to more clearly disclose the construction, operation, and useof the invention, reference should be had to the accompanying drawingsforming part of the present application.

Throughout the several figures of the drawings like reference charactersdesignate the same parts.

In the drawings: Figure 1 is a vertical cross section through theinvention complete, and as applied; Fig. 2 is a bottom plan View of thesame; Fig. 3 is a side elevation of the same; Fig. 1 is an enlarged,detail, sectional view of the fan mounting; and Fig. 5 is a diagrammaticview, showing the application of the invention.

The main objects of the invention are to produce a simple, economical,and durable fan ventilator with greatly increased efliciency.

Another object of the invention is to provide a ventilator which may beeasily, quickly, and accurately assembled, and equally well separated topermit of repairs, renewals of parts, cleaning, &c.

Referring to the drawings in detail, 1 indicates a stove pipe flue orconduit, in which the ventilator may be placed and through which thereis, normally, a considerable draft. This pipe is provided with anopening 2 in one side. About this opening is soldered or otherwisesecured a branch pipe 3 across which extends, diametrically, a bar orrod 4c, provided with a small socket or bearing adapted to freelyreceive the upper reduced end of a small shaft 5 provided with a hub 6from which extend radially a plurality of fan blades or vanes 7. Thelower end of the shaft 5 is reduced or pointed and seated in a socket orcavity formed in a bearing block of glass 8, or a block of other durablematerial. The bearing block is mounted in the bottom of a cup shapedsocket 9 extending from the upper end of a rod 10. The rod 10 is dividedinto three separate loop shaped arms 11 the outer ends of which areremovably clamped to a skirt flange 12 by means of small straps 13 whichare drawn into operative position by means of clamping bolts and nuts14. The skirt flange is formed as an integral part of the branch pipe 3.Thus, the rod or post 10 with its bearing block, may be securely held inoperative position to support the fan, and, of course, it may beadjustable vertically to properly seat the ends of the fan post 5 in itsbearings.

In order to increase the eifective draft of the fan, each blade isprovided with a downwardly and. outwardly bent arm 15 the lower end ofwhich projects slightly below the lower edge of the skirt flange. Toeach arm 15 is rigidly fixed a plate 16. The plates 16 are mountedtangentially to the circumference of the circle described by the lowerends of arms 15. Consequently, as the arms rotate, the plates 16 willact to draw the surrounding air inwardy toward the center of the circleand beneath the skirt flange. The rotating fan blades 7 then act to drawthis air rapidly upward and deliver it through branch pipe 3 and intopipe 1. In this way, a continuous inward and upward draft will beassured. In the preferred form, the transverse rod 4 is in the form of aremovable bolt, thus permitting all parts of the ventilator to bereadily and quickly removed.

In order to prevent particles of dust and other matter dropping backfrom the pipe 1 and into the branch 3, a deflector 17 is provided ineach of the pipes 1 adjacent each opening 2. This deflector is simply asmall plate extending upwardly and rearwardly across the opening 2 in aslightly inclined position, to create an upward current of the airpassing through the pipe 1, at these points, thus, carrying allparticles of dust or the like upwardly, beyond, and over the openingswithout dropping therein.

Preferably, a damper 18 is provided in each branch pipe 3 so that theymay be individually out off from the pipe 1, whenever desired.

The device is arranged in a branch pipe 2 connected to a flue pipe 1extending a long, or short distance from, the ceiling, or it may bearranged in a branch pipe extending across the top surface of a stove,preferably with the wide mouth end of the skirt flange extendingdownwardly to aid in the gathering and directing of the heated air,smoke, noxious gases &c.

The operation is as follows: The heated air with the smoke, noxiousgases &c. rises as is well known and a portion thereof enters the skirtflange which guides them to the vanes 7 between which they pass to theflue 1 and through this fine 1 to the atmosphere, or to any pointdesired. In passing between the fan vanes 7 however the hot air, gases,smoke &c. will rotate the same thereby causing the blades 16 attached tosaid vanes 7 to rotate therewith. These blades 16 in thus rotating drawall the surrounding hot air, smoke, noxious gases &c. near the ceilingof the room into the skirt flange from which they follow the courseabove described to the atmosphere. Thus it will be seen that the blades16 in rotating create a lateral draft thereby expediting the clearanceof all smoke, hot air, noxious gases &c. which would otherwise hangsuspended at or near the ceiling until they gradually work to and passthrough an ordinary opening or fan.

Changes may be made in the construction, arrangement, and disposition ofthe several parts of the invention without in any way departing from thefield and scope of the same and it is meant to include all such withinthis application wherein only a preferred form has been disclosed.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent is:

1. In combination, a pipe provided with a lateral opening, a branch pipesurrounding said opening, a fan revolubly supported in said branch pipe,and means carried by said fan for creating a lateral draft toward saidfan.

2. In combination, a pipe provided with a lateral opening, a branch pipesurrounding said opening, a fan revolubly supported in said branch pipe,arms carried by said fan, and lateral draft creating plates carried bysaid arms.

3. In combination, a pipe provided with a lateral opening, a deflectormounted in said pipe and extending above said opening, a branch pipesecured about said opening, a draft fan provided with means for creatinga lateral draft and means for supporting said draft fan in said branchpipe.

1. In combination, a pipe provided with a lateral opening, a branch pipesecured about said opening and provided with a skirt flange, a rodextending across the interior of said branch pipe and provided with asocket, a fan post provided with reduced ends one of which is adapted tobe seated in said socket, motor blades mounted on and turning said post,fan blades 16 secured to said post, a post provided with a cup socket, abearing block mounted therein and provided with a socket adapted to receive the other reduced end of the aforesaid fan post, looped armsextending from said post, and means for connecting said arms to theaforesaid skirt flange.

5. In combination, a pipe provided with a lateral opening, a branch pipesecured about said opening and provided with a skirt flange, a rodextending across the interior of said branch pipe and provided with asocket, a fan post provided with reduced ends one of which is adapted tobe seated in said socket, motor blades mounted on and turning said post,fan blades 16 secured to said post, a post provided with a cup socket, abearing block mounted therein and provided with a socket adapted toreceive the other reduced end of the aforesaid post, looped armsextending from said post, and means for adjustably clamping said arms tothe aforesaid skirt flange.

In witness whereof I have hereunto set my hand in the presence of twowitnesses.
